River Island Channel & Floodplain Restoration

Metro, a regional government body, contracted Inter-Fluve to restore an abandoned gravel mine on the Clackamas River. In 1996 a 100-year rain-on-snow flood event caused the mainstem Clackamas River to breach a levee and flow through this active gravel mining operation. Goals of the project included: to strategically implement restoration actions in areas where existing processes are insufficient to create or maintain highly functioning habitats, restoring perennially hydrologic connectivity to tributary habitats, and supporting multiple values including salmonids, stillwater species, and wildlife habitat, riparian and floodplain forests, water quality and recreation.

Estuary Restoration

Estuaries are dynamic ecosystems where oceans, rivers and human economies converge; they’re also critical to rearing grounds for fish and wildlife. Across the country, we’re reconnecting and restoring these habitats.
